Debugging Errors

named cookie not present

Debugging this issue is a bit hard. At least here is a step by step guide to debug the cookie handling on the browser.

I assume, you are using a Chrome-based Browser.

Requirements

• Before connecting to OpenVPN server, open a browser locally. On the new tab page, do right-click, inspect. The browser console appears. Important: click on the Network tab and ensure that "preserve log" is enabled.

• Ideally, you aren't logged on Azure with your main browser, otherwise you are not intercept the flow.

• Ensure, you have access to OpenVPN server logs in real-time. Tip: If you are using journalctl, use the option --no-pager. This prevents that large links are truncated.

Debugging Steps

1. Initiate connection to OpenVPN server, close the browser opened by OpenVPN client.
2. Goto OpenVPN server logs, grab the line with INFO_PRE,WEB_AUTH and copy the link with the full state.
3. Paste the link on the tab where the browser console is opened.
4. Continue the auth flow.
5. On the access-denied screen, check the Browser Console for any errors.
6. Then goto the Network tab again. There is a request with /oauth2/start or just start. Click on Cookies and check if the response cookie is present. Example Screenshot:
7. Then goto the Network tab again. There is a request with /oauth2/callback or just callback. Click on Cookies and check if the request cookie is present. Example Screenshot:
